◊ DIGITAL SIGNATURE STANDARD
Digital Signature Standard
The {NIST}'s {standard} for {digital
signatures} (authenticating both a message and the signer)
that was first announced in 1991. It is based on an
{algorithm} using {discrete logarithms}, which is a variant of
the {Elgamal algorithm} with Schnorr's improvements. DSS's
security is currently considered very strong - comparable to
{RSA}. It is estimated that DSS's 1024-bit keys would take
1.4E16 {MIPS}-years to crack.
